System and Method for Toll Transactions Utilizing a Distributed Ledger

ABSTRACT

An electronic toll data collection management system comprises a plurality of nodes, wherein at least one of the plurality of nodes is a toll collection point, wherein the toll collection point comprises: a computing system; and a receiver; wherein each of the plurality of nodes has access to a copy of a distributed ledger, wherein the processor of each of the plurality of nodes is configured to: utilize blockchain protocols to verify and record a transaction occurring within the distributed ledger; parse through the blockchain to locate the block containing the transmitted data from the transmitter, de-encrypt the block, and extract the data; and encrypt a new block indicating a debit to an account of an operator of a vehicle, wherein the account is identifiable through the transmitted data from the transmitter.

BACKGROUND OF THE INVENTION

Toll roads may facilitate the passage of a large volume of vehiclesevery day. Traditionally, there is a toll collection point along a giventoll road wherein an operator of a vehicle must pay a toll (i.e., avariable fee) for passage along the road. To reduce time spent at a tollcollection point and to increase efficiency, these toll collectionpoints have increasingly become unmanned stations that rely onelectronic toll collection systems.

Electronic toll collection systems have become increasingly popularsince participation in the system allows an operator to bypass cash-onlytoll collection points that usually take more time to pass through. Anoperator of a vehicle may choose to create an account with a companymanaging an electronic toll collection system. Upon creating an account,the operator may receive a transmitter to be placed in the vehicle.Typically, as a vehicle gets close to a toll collection point, thetransmitter transmits information to a receiver. A camera may verify theinformation being transmitted by capturing a picture of the vehicle.Both the transmitted information and the captured image may be sent toan information handling system. There may be a central informationhandling system dedicated to transaction processing. Electronic tollcollection systems may operate on four main components: automatedvehicle identification, automated vehicle classification, transactionprocessing, and violation enforcement. Often, companies contract outeach of these components to handle separately. Independent companies maynot have access to the overarching company's database that manages theelectronic toll system, or other independent companies' databases.

Thus, there is a need for a system that utilizes a distributed ledgerthat may access, process, and manipulate the data acquired at a tollcollection point.

DETAILED DESCRIPTION OF THE PREFERRED EXAMPLES

The present disclosure relates to implementing an electronic toll datacollection management system in a decentralized computing network thatemploys a distributed ledger. More particularly, examples of a systemand method are disclosed for processing vehicle and financialinformation as an operator passes through a toll collection point. Thedecentralized computing network may include a plurality of computingsystems that act as nodes. Each node may access the distributed ledger.In examples, the distributed ledger may utilize blockchain technologyand protocols.

FIG. 1 illustrates an example of a decentralized computing network 100.Decentralized computing network 100 may include a plurality of nodes105. Node 105 may be operated by an individual, company, and/or otherentity. Each node 105 may include a processor, a memory unit, and a bus.The memory unit may be volatile and/or non-volatile. Further hardwareand/or software may be used by each node 105. Additionally, any suitableinput and output (I/O) devices may be implemented. Without limitation,node 105 may be a computer. Concerning the present disclosure,computer-readable storage mediums may be utilized.

Decentralized computing network 100 may connect the plurality of nodes105 by any form or medium of digital data communication such as acommunication network. Without limitation, a communication network mayinclude a local area network (“LAN”), a metropolitan area network(“MAN”), a wide area network (“WAN”), peer-to-peer networks (structured,unstructured, and/or hybrid models), grid computing infrastructures, theInternet, and/or combinations thereof.

In examples, decentralized computing network 100 may utilize blockchaintechnology and protocols for the distributed ledger. However, not alldistributed ledgers may necessarily employ blockchain technology tosuccessfully provide secure and valid achievement of distributedconsensus. Without limitation, a blockchain may be one type of datastructure considered to be a distributed ledger. A blockchain may be acontinuously growing list of records. In examples, the records may berepresented as blocks. Each block may include transaction data, a hashpointer, a timestamp, and/or combinations thereof. These blocks may belinked and secured using cryptographic measures. Cryptographic measuresmay include any suitable mathematical algorithm In examples, a hashfunction may be used as the cryptographic measure, wherein the hashfunction is a mathematical algorithm that takes a data input andgenerates a fixed output (e.g., a bit string with a fixed length). Hashfunctions may have pre-image resistance, wherein it may be infeasible toinvert without using a brute-force method of trying to compare hashedvalues of random inputs. Hash functions may be collision resistant,wherein it may be infeasible for two given inputs to produce the sameoutput. In examples, a hash function may be designed to be a one-wayfunction.

The methodology behind blockchain may promote a decentralized networkover a peer-to-peer network rather than a central computing system. Inexamples, the plurality of nodes 105 may own a full copy of thedistributed ledger. When a transaction occurs in the distributed ledger,the plurality of nodes 105 may verify the status of the distributedledger (i.e., the addition of a new block). A consensus among theplurality of nodes 105 may be required to verify the status of thedistributed ledger. Any suitable protocol may be used to reachconsensus. Without limitation, suitable protocols may be proof of work,proof of stake, proof of authority, and/or combinations thereof. Inexamples, this may occur automatically and/or continuously. Onceconsensus has been reached, the distributed ledger may be updated (i.e.,the addition of a block).

In examples, digital signatures may be used in the blockchain. Inexamples, a public and private key may be created using an algorithm andmay be related to each other. The public key may be distributed to theplurality of nodes 105. The private key may be kept by an individualnode 105 to digitally sign any transaction occurring in the distributedledger. The receiving party of a transaction that has been signed mayverify the data within the transaction by using the public key. One ofordinary skill in the art would recognize that any known digitalsignature systems may be used without departing from the spirit andscope of the present invention.

FIG. 2 illustrates an example of a blockchain 200. There may be aplurality of blocks 205 within blockchain 200. In examples, a firstblock 210 may represent the first data transactions within thedistributed ledger. The first block 210 may include any suitable size ofdata. A hash function may be used to generate an output value (e.g., a“hash”) from the first data transactions. For each subsequent block 205added to blockchain 200, the input to the hash function of the new blockmay include the previous block's hash and the data transactionsrepresented by the new block. This may produce a system wherein theplurality of blocks 205 are linked, in sequential order, by the previousblock's output value of the hash function. The linked blocks 205 mayallow the plurality of nodes 105 (referring to FIG. 1) to followblockchain 200 backwards, from progression, in order to observe andverify data transactions. In examples, any suitable data miningtechnique may be used to verify and/or create the addition of a block inblockchain 200.

In examples, a fork 215 may be created within blockchain 200. This maybe when blockchain 200 diverges into two potential paths of progression.Without limitation, fork 215 may be introduced when two blocks 205 areadded that claim the hash of the previous block, when an invalidtransaction occurs, and/or when new protocols are implemented. In theexample wherein fork 215 is introduced due to two blocks being added, aportion of the plurality of nodes 105 (referring to FIG. 1) may allocatecomputational efforts in adding blocks onto one side of fork 215. Theremaining portion of the plurality of nodes 105 may allocatecomputational efforts in adding blocks onto the other side of fork 215.One side of fork 215 will inevitably surpass the other in length. Theplurality of nodes may come to an agreement that the longer side of fork215 is the legitimate path of progression of blockchain 200. Inexamples, the path of progression on the other side of fork 215 may bedeemed invalid, may be abandoned, and/or data transactions within theblocks may be lost. In examples with accordance to this disclosure,blockchain 200 may be able to accommodate forks.

In examples, the distributed ledger may be private, public, and/orcombinations thereof. The electronic toll data collection managementsystem may have access to information that an operator of a vehicle maynot want publicly disclosed (i.e., vehicle information, information on adriver's license, financial information, etc.). There may be differenttypes of nodes 105 (referring to FIG. 1) in the electronic toll datacollection management system. There may be limited access within thedistributed ledger based on the type of node 105 in operation. Withoutlimitation, different types of nodes 105 that may interact within theelectronic toll data collection management system may be the companyregulating the toll road, other companies, the general public, thegovernment, and/or combinations thereof. In examples, the distributedledger may be shared and/or compatible with distributed ledgers and/ordatabases belonging to other entities. This may allow cross-referencingbetween entities.

In examples, smart contracts may be used within the distributed ledger.Smart contracts may be computer protocols to execute the agreed uponterms of a contract. Smart contracts may be partially and/or fullyself-executing. In examples, smart contracts may be written as code inblockchain 200. Transactions within a smart contract may be reflected inblockchain 200 as the plurality of nodes 105 (referring to FIG. 1)receive the data transactions, verify the information, and update theirrespective copies of the distributed ledger.

FIG. 3 illustrates an example of a toll collection point 300. Tollcollection point 300 may serve to collect a fee to be paid in order tocontinue travelling along a path (i.e., a toll road). In examples, anoperator of a vehicle 305 may have created an account with a companyregulating the toll road. A new block 205 may be added to blockchain 200(referring to FIG. 2) that reflects the creation of an account betweenthe operator and the company. The account may contain informationprovided by the operator. Without limitation, the information providedmay include vehicle make and model, vehicle registration number, year ofvehicle manufacture, license plate number, driver's license number,operator contact information, billing information for the operator,operator permanent address, and/or combinations thereof. Traditionally,this information may be stored in a database at a central computingcenter. In examples within the present disclosure, this information maybe contained in the new block 205, or a subsequent block 205. Inexamples, the creation of the account may have been done through a smartcontract between the operator and the company, wherein the smartcontract is recorded in blockchain 200 (referring to FIG. 2). Agreedupon terms may include initially depositing a certain amount of moneyinto the account and debiting the account a certain fee every time theoperator passes through toll collection point 300 along a toll road.Further agreed upon terms may include breach-of-contract payments and/orprocesses. In examples, the smart contract may partially self-executeuntil the terms have been fulfilled. In exchange for creating anaccount, the company may provide the operator with a transmitter 310.

Transmitter 310 may be any suitable device capable of producingelectromagnetic waves. Transmitter 310 may include and utilize anysuitable hardware and/or software to produce electromagnetic waves. Theelectromagnetic waves may travel at a specified frequency. Transmitter310 may be any suitable size, height, and/or shape. In examples,transmitter 310 may be in the shape of a card. Transmitter 310 may beplaced anywhere within or on vehicle 305. Without limitation,transmitter 310 may use radio-frequency identification (RFID).Transmitter 310 may passively or actively operate. In examples,transmitter 310 may operate to produce an electromagnetic wave afterreceiving enough energy emitted from a receiver in a certain proximity.In alternative examples, transmitter 310 may include a power source foractive operation. Any suitable power source may be used to induceoperation of transmitter 310.

As vehicle 305 passes by and/or through toll collection point 300,transmitter 310 may transmit data via electromagnetic waves to areceiver 315. In examples, the transmitted data may be a serial numberfor the operator's account. In alternative examples, the transmitteddata may contain information within the operator's account. There may bea plurality of receivers 315. Receiver 315 may be any suitable size,height, and/or shape. Receiver 315 may process the incomingelectromagnetic waves and convert them into electrical currents.Receiver 315 may include and utilize any suitable hardware and/orsoftware to receive and process electromagnetic waves. The electricalcurrents containing the data transmitted by the electromagnetic wavesmay travel into a computing system 320.

Computing system 320 may include similar components as node 105(referring to FIG. 1). Computing system 320 may include a processor, amemory unit, and a bus. The memory unit may be volatile and/ornon-volatile. Further hardware and/or software may be used by computingsystem 320. Additionally, any suitable input and output (I/O) devicesmay be implemented. Without limitation, computing system 320 may be acomputer. Concerning the present disclosure, computer-readable storagemediums may be utilized.

In examples, computing system 320 may act as node 105 (referring toFIG. 1) in the disclosed electronic toll data collection managementsystem. Computing system 320 may broadcast the data received aselectrical currents to the distributed ledger. In examples, theplurality of nodes 105 (referring to FIG. 1) may verify and update theirrespective copies of the distributed ledger, within the electronic tolldata collection management system, that the operator of vehicle 305 haspassed by and/or through toll collection point 300 at a certain time.The smart contract in place within blockchain 200 (referring to FIG. 2)may partially self-execute when this data is processed. In examples,this self-execution may debit the operator's account a specified amountfor the toll fee. The plurality of nodes 105 (referring to FIG. 1) mayfurther verify and update their respective copies of the distributedledger that the operator's account has been debited by the companyregulating the toll road. Concerning the present disclosure, theimplementation of the electronic toll data collection management systemmay negate the need for central databases to store and update aregulating company's customer data.

Toll collection point 300 may further include a camera 325. Camera 325may take a picture of vehicle 305 as it passes through toll collectionpoint 300. Camera 325 may be any suitable device or sensor, orcollection of hardware and/or software, for capturing an image asvehicle 305 passes by. Camera 325 may implement laser scanners. Inexamples, this picture may be used to verify the information transmittedby transmitter 310. The picture may be sent to computing system 320 tobe broadcast to the plurality of nodes 105 (referring to FIG. 1) withinthe electronic toll data collection management system. The plurality ofnodes 105 may verify this transaction and update their respective copiesof the distributed ledger.

In examples, an operator may create an account with the regulatingcompany of a toll road but may not receive a transmitter. In thisparticular example, camera 325 may take a picture of vehicle 305 as itpasses through toll collection point 300. The picture may be sent tocomputing system 320 to be broadcast to the plurality of nodes 105(referring to FIG. 1) within the electronic toll data collectionmanagement system. The plurality of nodes 105 may verify thistransaction and update their respective copies of the distributedledger. In examples, the electronic toll data collection managementsystem may employ automated vehicle identification protocols. Thepicture taken may be analyzed to extract the license plate number ofvehicle 305. A legible license plate number may be extracted from thepicture, depending on the quality of the picture. In other examples, alicense plate number may not be extracted as outside factors may producea poor image of vehicle 305 (i.e., inclement weather). A request may bebroadcast over the distributed ledger to find the account containing theextracted license plate number. Blockchain 200 (referring to FIG. 2) maybe parsed through to find the matching account. The matching account maybe debited a specified amount for the toll fee. The plurality of nodes105 (referring to FIG. 1) may further verify and update their respectivecopies of the distributed ledger that the matching account has beendebited by the company regulating the toll road.

In examples, an operator of vehicle 305 may not have created an accountwith the company regulating the toll road. Subsequently, the operatormay not have obtained a transmitter 310 to transmit data to theelectronic toll data collection management system. As the operatorpasses through toll collection point 300, no data may be transmitted toreceiver 315. In examples, camera 325 may take a picture of vehicle 305as it passes through toll collection point 300. In examples, a“pay-by-mail” system may be used by the regulating company which may runbased off a similar concept. The picture may be sent to computing system320. Computing system 320 may flag the picture of vehicle 305 asbelonging to an operator who has not opened an account with the companyregulating the toll road and/or who has not payed the toll. The flaggedpicture may be broadcast to the plurality of nodes 105 (referring toFIG. 1). The plurality of nodes 105 may verify this transaction andupdate their respective copies of the distributed ledger.

In examples, the operator of a vehicle within a flagged picture stillowes the company regulating the toll road a fee for travelling on it.The regulating company may contract out the function of acquiringpayments from operators who do not pay the fee to other companies (i.e.,collection agencies). In examples, operators who refuse to pay the feeor do not pay within a specified time may be prosecuted. In thisparticular example, the government and/or law enforcement may becomeinvolved. Concerning the present disclosure, the distributed ledger mayprovide an indisputable record for any party involved in a dispute(i.e., questioning whether or not the operator had passed through a tollcollection point 300).

It may be difficult for companies to find information on the operator ofthe vehicle based on a picture taken of that vehicle. It may take daysand/or weeks to process the image, extract useable information, searchpublic databases to find contact information for the operator, and billthe operator. Concerning the present disclosure, the electronic tolldata collection management system may reduce time and costs and increaseefficiency.

In examples, the electronic toll data collection management system maybe accessible to a plurality of nodes 105 (as discussed above). A firstnode 105 acting on behalf of the regulating company may search throughblockchain 200 (referring to FIG. 2) to find information concerningoperators who have not paid back the regulating company for accessingthe toll road. In examples, first node 105 may act on behalf of anotherparty. In examples, this information may be a flagged picture. Firstnode 105 may de-encrypt the block 205 containing that information. Firstnode 105 may extract that information. First node 105 may enter into asmart contract with a second node 105. In examples, second node 105 mayact on behalf of a government agency. First node 105 may request thatsecond node 105 use the extracted information to match it with otherinformation. In examples, first node 105 may request second node 105 toacquire a specific operator's contact information and permanent address.Without limitation, other information may be requested if required bythe regulating company. Second node 105 may run the extractedinformation through an external database. In examples, the externaldatabase may contain data matching that of the extracted information.The matching data may provide additional information that the first node105 had requested. Second node 105 may broadcast this additionalinformation to blockchain 200. The plurality of nodes 105 may verifythis transaction and update their respective copies of the distributedledger. First node 105 may now be able to contact an operator of avehicle within a flagged picture by utilizing this new data.

In examples, first node 105 may enter into a smart contract with secondnode 105 prior to extracting information from a block. The agreed uponterms may allow second node 105 to parse through blockchain 200(referring to FIG. 2) to gather the information to be run in an externaldatabase. Second node 105 may be granted access to de-encrypt therelevant block 205. Second node 105 may extract the information to berun in the external database. In examples, second node 105 may fulfillthe terms of the smart contract as previously discussed.

In examples, an operator of vehicle 305 may not need to create anaccount with the company regulating the toll road. There may be abarrier (not illustrated) blocking a road lane. The barrier may notpermit the operator of vehicle 305 from passing through unless physicalcurrency is deposited at toll collection point 300. In examples, as theoperator deposits physical currency at toll collection point 300,computing system 320 may record this transaction. Computing system 320may move the barrier blocking the road lane so as to allow the operatorof vehicle 305 to pass through. Computing system 320 may broadcast thedeposit of physical currency and/or the raising of the barrier to theplurality of nodes 105 (referring to FIG. 1) within the electronic tolldata collection management system. The plurality of nodes 105 may verifythis transaction and update their respective copies of the distributedledger.

In examples, the distributed ledger may be categorized by type of inputdata. In alternative examples, the distributed ledger may be a singleblockchain 200 (referring to FIG. 2) that includes all data. Separateblockchains 200 (referring to FIG. 2) may be created to represent datawithin specific categories. Without limitation, some of these categoriesmay be an operator's financial information, the transmitted datareceived from transmitter 310, vehicle information, and/or combinationsthereof. In examples, some blockchains 200 may only be accessed by thegovernment and/or law enforcement agencies. In examples, a separateblockchain (referring to FIG. 2) may be utilized specifically formaintaining records on operators of vehicles 305 who have not paid tollsas they pass through toll collection points 300. In examples, a separateblockchain 200 (referring to FIG. 2) may be utilized to utilize dataprovided by law enforcement agencies and/or the government. Nodes 105(referring to FIG. 1) operating under law enforcement agencies and/orthe government may be granted access within a smart contract to use datarelated to violators who do not pay the toll and/or may be able to inputdata from their own databases into the blockchain 200. In examples, theregulating company may interact with law enforcement and/or thegovernment through the distributed ledger.

As previously discussed, first node 105 and second node 105 may enterinto a smart contract to acquire missing information and/or to matchdata together. In previous examples, first node 105 may extract specificdata from blockchain 200 (referring to FIG. 2) and provide that data tosecond node 105. Second node 105 may then search external databases formatching data and upload the matched data to blockchain 200 (referringto FIG. 2) so first node 105 may have access. In other previousexamples, second node 105 may extract specific data from blockchain 200(referring to FIG. 2), search external databases for a match, and uploadmatched data to blockchain 200 (referring to FIG. 2). In alternativeexamples, first node may parse through a first blockchain 200,de-encrypt the appropriate block 205 (referring to FIG. 2), extract therelevant data, and provide that data to second node 105. Second node 105may then parse through a second blockchain 200 to find matching data,de-encrypt the appropriate block 205 (referring to FIG. 2), extract thematching data and/or any relevant information, and provide that data tofirst node 105. In alternative examples, second node 105 may parsethrough the first blockchain 200 that contains the data to be utilizedand may parse through the second blockchain 200 to find matching data.Second node 105 may locate the appropriate block 205 (referring to FIG.2), de-encrypt it, extract the relevant data, and provide it to firstnode 105. First node 105 may transfer that data to a separate blockchain200. First node 105 and/or second node 105 may broadcast the matcheddata to a separate blockchain 200. The plurality of nodes 105 (referringto FIG. 1) may verify this transaction and update their respectivecopies of the distributed ledger.
